What is iso flange? In addition to the KF flange and CF flange series of accessories in high vacuum systems, there are ISO flange series also used in high vacuum systems.The difference between ISO and KF is that the size is different from the type of some parts. The common forms of ISO flange are ISO-K and ISO-F. It is a kind of quick-release flange used in vacuum system. It is used in high vacuum system. The accessories are used to connect the high vacuum chamber through the vacuum process piping, and are also suitable for stainless steel pipes or stainless steel hoses welded in the vacuum piping piping. 1. ISO Flange Material
ISO flanges are usually made of 304, 304L and 306 stainless steel, which have the advantages of acid and alkali resistance, corrosion resistance, high temperature resistance, high pressure resistance, high hardness and not easy to rust;
ISO flange sealing materials are usually viton, buna, silicone, epdm, aluminum, etc., using fluorine rubber material, can withstand 150 ℃ baking; Compared with the KF series vacuum sealing ring, the ISO series sealing ring has an aluminum spring outer ring in addition to the center bracket and the fluorine rubber sealing ring, and its main function is to prevent the sealing ring from slipping.
Other materials can be customized according to customer needs.
2. ISO Flange Application
In addition to general vacuum piping, ISO vacuum flanges are also used in ultra-high vacuum process environments.
Application Range: chemical industry, electric power, aerospace, IT industry, semiconductor industry, new energy, medicine and biological engineering, metallurgy, welding, heat treatment and other fields.
